Potassium humate is a high-efficiency organic potassium fertilizer, because the humic acid in it is a biologically active agent, which can increase the content of available potassium in the soil, reduce the loss and fixation of potassium, increase the absorption and utilization of potassium by crops, and also improve soil , Promote crop growth, improve crop resistance, improve crop quality, protect agricultural ecological environment and other functions;

The application method of potassium humate

Seed soaking: the concentration of the two kinds of fertilizers for soaking seeds is 0.05%-0.005% (effective content), the rice seeds are soaked for more than 48 hours, the wheat seeds are soaked for 8-10 hours, and the corn seeds are soaked for about 24 hours. The soaking temperature is best kept at about 20°C.

Soaking roots, dipping roots, dip strips: When transplanting crops or fruit tree cuttings such as rice, sweet potatoes, vegetables, etc., use them to dip roots, dip strips, or mix liquid manure and soil to make a paste dipping roots when transplanting. The concentration of root dip is 0.01%~0.05%, and the concentration of dip root can be slightly higher. The soaking time is generally 10 to 24 hours, and the time can be shortened when the temperature is high.

Topdressing outside the roots: Use potassium humate or sodium humate to spray the leaves and ears with an aqueous solution of rice, wheat and other crops from blooming to the filling stage, which can promote filling and make the grain plump. Extra-root topdressing is carried out in the early stage of flowering and filling of wheat, rice, etc., with 50 kg of liquid manure per mu with a concentration of 0.01% to 0.05%.
